It is recommended that customers check with their regulatory agency to determine which biodegradation testing is required to make product performance claims about a product’s biodegradability.

Biodegradability testing can be performed for aerobic or anaerobic biodegradability; for aerobic biodegradation, customers most commonly request OECD 301B for Ready biodegradability and OECD 302B for Inherent biodegradability.
